Definitions

  • the invention relates to a towing hitch for a towing vehicle, comprising a base body, a coupling unit with a coupling element, which is intended to cooperate with a counter-coupling element of a trailing vehicle, wherein the coupling unit is adjustable relative to the base body between a coupling position and a release position, and a securing device with a securing element, which is adjustable between a securing position and a release position, wherein it secures the coupling unit in its coupling position in its securing position.
  • a stable position is understood, which can take a body and in which he persists, as long as no further external events occur, him again from this stable position to solve.
  • a simple spring-loaded detent pin as he, for example, from the EP 1 586 469 A1 is known, according to this understanding, although a securing position in which he is able to secure the coupling unit in the coupling position, but no release position in which he allows a transfer of the coupling unit from its coupling position in its release position. He would namely return immediately after his retraction under the influence of the spring bias back into the recess of the coupling unit and thus prevent the transfer of the coupling unit from its coupling position in the release position.
  • a generic trailer hitches is for example from the DE 10 2006 011 676 known.
  • this hitch occurs when coupling a trailing vehicle, the counter-coupling element directly with a component of the securing device in contact to the transfer of the To cause coupling element from the release position in the coupling position. Since the position and orientation of the counter-coupling element relative to the trailer coupling and thus to the safety device depend on the one hand on the nature of the trailing vehicle and on the other of its orientation relative to the towing vehicle, it can come in practice Ankuppelvorêtnic in which the counter-coupling element is not in capable of properly triggering the securing device.
  • a towing hitch of the type mentioned in which the securing element in its release position allows a transfer of the coupling unit from its coupling position in its release position, and in which the securing element by the coupling unit in the course of their movement from the release position to the coupling position deflected from the release position and transferred to a securing position preparation state and then, when the coupling unit has reached the coupling position, automatically goes into the securing position.
  • the safety device is therefore triggered by a member belonging to the trailer coupling, namely the coupling unit, which is securely guided in the main body of the trailer coupling and thus follows a predefined and reliably reproducible sequence of movements in the trailer coupling.
  • a structurally simple, in its function but effective construction of the securing device can be achieved in that on the securing element, a trigger element is movably mounted, which is biased in a stop position, wherein the trigger element of the coupling unit in their movement from the coupling position to the release position below Leave the fuse element in its release position is deflected from the stop position, while it remains in a movement of the coupling unit from the release position in the coupling position relative to the securing element in the stop position and transferred the securing element in the securing position preparation state.
  • a triggering element is provided on the main body of the hitch and therefore can not act as directly on the safety lever, as this is a movable element on the securing element mounted triggering element.
  • the securing device further comprises a locking element which is adjustable between a locking position and an unlocking position, wherein the locking element holds the securing element in its locking position in its locking position, and in its adjustment in the unlocked position transfers the securing element in its release position.
  • a blocking element By means of such a blocking element, it can be ensured, in particular during driving, that the securing element does not move out of the securing position unintentionally and automatically.
  • the blocking element is latched in its unlocked position on the securing element, wherein this latching can be achieved preferably in the transfer of the securing element from its release position in the securing position preparation state.
  • the reliability of the trailer coupling can be further increased by the fact that the locking element is biased in its locking position.
  • the reliability of the trailer coupling can also be further increased by the fact that the locking element in its adjustment in the locked position transferred the fuse element in its backup position.
  • drive means For the adjustment of the locking element from the locking position into the unlocking position suitable drive means may be provided. These drive means may be formed for example by a manual operating lever, on the pivot axis of the locking element is arranged rotatably.
  • a further simplification of the structural design of the trailer coupling according to the invention can also be achieved in that the securing element is pivotally mounted on the base body and / or that the trigger element is pivotally mounted on the fuse element and / or that the blocking element is pivotally mounted on the base body.
  • a display device which indicates whether the securing element is in the securing position.
  • the display device may for example comprise a display pin which is deflectable by the securing element from a position in which it indicates that the securing element is in the securing position.
  • the display device for example, the display pin, a sensor unit to be assigned, wherein the output signal of the sensor unit, for example, for the purpose of a remote display of the position the security device can be used.
  • the hitch invention may also have two redundant security devices. Although this is preferred, the two security devices need not be completely separate from each other. Rather, it is conceivable that the blocking element is associated with the securing elements of both securing devices together.
  • orientation and directional indications relate to the normal operating condition of the towing hitch, in which it is mounted on a towing vehicle, wherein “front” coincides with the usual direction of travel of the towing vehicle.
  • FIG. 1 a hitch according to the invention is generally designated 10.
  • the presentation of the FIG. 1 shows a side sectional view of the hitch 10, wherein the "up-down” direction corresponds to the drawing plane of the vertical axis H of the hitch 10, the "right” direction corresponds to the drawing plane of the direction of travel F of the towing vehicle, ie the "left-right” Direction of the plane of the longitudinal axis L of the hitch 10 corresponds, and the orthogonal to the plane extending direction of the transverse axis Q of the hitch 10 corresponds.
  • a coupling unit 14 is disposed about an axis A extending substantially in the transverse direction Q between a coupling position (see FIG FIGS. 1 and 2 ) and a release position (see Figures 3 . 4 and 5 ) pivotally mounted.
  • the coupling unit 14 comprises a coupling element 16, in the present case a ball head, which is designed and configured to cooperate with a counter-coupling element 18, in the present case a ball socket.
  • the Ball socket 18 is part of a drawbar 20 of an in FIG. 1 only roughly schematically indicated trailing vehicle 22.
  • the trailer coupling 10 via fastening bolts 24 at an in FIG. 1 only roughly schematically indicated towing vehicle 26 attached.
  • the hitch 10 further includes a driver element 28 which is also pivotally mounted about the pivot axis A.
  • a tension spring 30 engages with its one end below the pivot axis A on the driver element 28 and with its other end to the coupling unit 14.
  • the coupling unit 14 is L-shaped, wherein at the free end of an L-web 14a of the ball head 16th is arranged and the free end of the other L-web 14 b adjacent the point of application for the tension spring 30 is arranged. In this way, the driver element 28 of the tension spring 30 when the driver element 28 otherwise no other external forces acting pulled with a shoulder 28a in abutment against a stop pin 14c of the clutch unit 14.
  • the pivot axis A is further surrounded by a torsion spring 32, whose one end engages the base body 12 and the other end engages the driver element 28.
  • the torsion spring 32 is arranged such that it the driver element 28 in FIG. 1 biased counterclockwise. Can follow the driver element 28 of this bias, because there are no further external forces acting on it, so it is under the bias of the torsion spring 32 in the in the Figures 3 and 4 shown transferred position and takes in the course of this movement due to the interaction of the shoulder 28a with the stopper pin 14c, the coupling unit 14 in the release position.
  • the entrainment element 28 has two side parts 28b and a bridge part 28c connecting the two side parts, wherein it is provided with the two side parts 28b, as in FIG FIG. 7 is shown, on both sides of the coupling unit 14 is pivotally mounted on the pivot axis A.
  • the driver element 28 as Punched and bent part made of sheet metal.
  • the driver element 28 may also be reinforced by welded sheet metal elements if necessary.
  • the driver element 28 may also be produced as a forged part or composed of a plurality of individual parts, which are connected to each other, for example by screws, rivets, welding or the like.
  • each of the two side parts 28b of the driver element 28 is assigned a separate spring 30. Accordingly, the coupling unit 14 both on their right in the direction of travel F and on its left side each have a point of attack for a spring 30 and a respective stop pin 14c, and has each of the side parts 28b via a stop 28a.
  • the loading ramp 34 has centrally at its end projecting into the housing body 12 a recess 34b, which allows the ball head 16, in a position below the loading ramp 34 provided space 12 a of the housing body 12 to be received (see FIG. 3 ).
  • the coupling unit 14 is held and secured by a securing device 40 in its coupling position. Structure and function of this securing device 40 will be described below with reference to the FIGS. 1 and 8a to 8e be explained in more detail.
  • the securing device 40 comprises a securing element or a securing lever 42, which is mounted on the housing body 12 so as to be pivotable about an axis B extending essentially in the transverse direction Q.
  • the free end 42a of the securing lever 42 is in contact with a contact surface 14d of the second L-web 14b of the coupling unit 14. In this way, the locking lever 42 prevents positive locking, that the coupling unit 14 moves out of the coupling position in an undesirable manner automatically.
  • a locking element or a locking cam 48 is provided which rests with a nose 48a on a first locking surface 42b of the safety lever 42.
  • the securing position of the safety lever 42 is further defined by mutual engagement of a contact surface 42d of the safety lever 42 and a contact surface 12b of the housing body 12.
  • the locking cam 48 is rotatably connected to a manual lever 46 relative thereto, but pivotally connected thereto about the substantially transverse axis C. Furthermore, the locking cam 48 biased by a spring 50 in this locking position. With its one end, the spring 50 engages at a location of the locking cam 48, which is arranged between the pivot axis C and the nose 48 a. With its other end, the spring 50 engages a trigger element or latch element 44, which is mounted on the securing lever 42 so as to be pivotable about an axis D extending essentially in the transverse direction Q. Under the action of the spring 50, this pawl member 44 is biased against a stop 42 c of the safety lever 42.
  • a projection 48b is provided on the locking cam 48, which abuts the housing body 12 and prevents further pivoting of the manual operating lever 46.
  • the locking lever 42 of the second locking surface 42e adjacent 42g is formed so high that for the nose 48a of the locking cam 48 is always an opposite surface of the safety lever 42 is provided.
  • FIG. 8d The condition thus obtained is in FIG. 8d shown. It corresponds to the uncoupled state in which the trailer coupling 10 is at the same time ready for the renewed coupling of a trailing vehicle 22.
  • the second L-web 14b of the coupling unit 14 again enters the region of the pawl member 44. Since this is in the stop position and now a movement of the clutch unit 14 in the clockwise direction can not escape, the pawl member 44 remains in its position so that the coupling unit 14 not only the pawl member 44, but with it the entire safety lever 42 has to swing out of the way, as in FIG. 8e is shown.
  • the nose 48a of the locking cam 48 disengages from the second locking surface 42e of the locking lever 42 and engages the control surface 42f of the locking lever 42. Under the influence of the spring 50, the nose 48a slides on the control surface 42f along and thereby pivots the safety lever 42 in a clockwise direction.
  • the coupling state of the hitch 10 is indicated to the operator by a display 52.
  • This display device 52 may for example comprise a display pin 52a, which is received in a recess 52b of the housing body 12 and biased by a spring 52c into the recess 52b inside.
  • the safety lever 42 has a projection 42h (see FIG. 8c ) which acts on the indicator pin 52a and pushes it out against the biasing force of the spring 52c from the recess 52b. Only when the upper end 52d of the indicator pin 52a is flush with the edge of the recess 52b, as shown in FIG. 8a is shown, there is the trailer coupling 10 and its coupling unit 14 in the coupled and secured state.
  • the hitch 10 may also be designed remotely operable.
  • the manual override lever may be at a position away from the hitch 10 are arranged and acting on the Spernocken 48 bearing and the pivot axis C forming shaft via a Bowden cable.
  • a motor drive for example an electric motor, a pneumatic and / or hydraulic unit or the like, the locking cam 48 from the in FIG. 8a position shown in the in FIG. 8b transferred position shown.
  • the display device 52 may be replaced or supplemented by a sensor that drives a corresponding display in the vicinity of a switch for actuating the motor drive.
  • the hitch 10 according to the invention can have two separate securing devices 40. So you can see for example in the plan view FIG. 6 Although this is preferred, the two securing devices 40 do not need to be completely separate from one another. Rather, it is conceivable that the pawl member 44 is associated with the safety levers 42 of both securing devices 40 together. Thus, the pin forming the axis D can connect the two securing levers 42 to one another, wherein the catch element 44 can be arranged between the two securing levers 42. In this case, at the end face 14e of the coupling unit 14 in the center a separate nose 14f (see FIG. 8e ) may be provided for engagement with the pawl member 44. Further, two springs 50 may be provided in this case.
  • the center of the ball head 16 is not located exactly vertically above the pivot axis A of the clutch unit 14, but is seen slightly behind the pivot axis A seen in the direction of travel.
  • the horizontal distance X of the center of the ball head 16 from the pivot axis A ie, the distance of the projection taken in the vertical direction of the center of the ball head 16 in a pivot axis A containing, horizontal plane from the pivot axis A, preferably at most 1/40 of the diameter of the ball head 16, ie at a ball head of 80 mm diameter at most 2 mm.
  • Generally 16 values between 80 mm and 110 mm are usual for the diameter of the ball head.
  • the forces exerted on the or the locking lever 42 forces can be kept low.
  • the dynamic vertical load of the ball socket 18 when driving or its static load at standstill of towing vehicle 26 and trailing vehicle 22 is substantially completely introduced into the pivot axis A of the coupling unit 14 and need not be taken up by the safety lever 42.
  • the clutch unit 14 always in contact with the safety lever 42 holds, the ratio Y / X of the horizontal distance Y between the pivot axis A of the coupling unit 14 and the center of the contact surface 14d between locking lever 42 and coupling unit 14 to the above-defined horizontal distance X of the center of the ball head 16 from the pivot axis A has a value of between about 25 and about 70. Since the center of the ball head 16 and the center of the contact surface 14d are on different sides of the pivot axis A, the vertical load of the ball socket 18 always tries to pivot the coupling unit 14 from the coupling position in the direction of the release position.
  • the hitch 10 also has two balancing devices, namely a balancing device 54 to compensate for the vertical coupling clearance between the ball head 16 and the ball socket 18 and a compensating device 56 to compensate for the movement of the clutch unit 14 in its coupling position.
  • a balancing device 54 to compensate for the vertical coupling clearance between the ball head 16 and the ball socket 18
  • a compensating device 56 to compensate for the movement of the clutch unit 14 in its coupling position.
  • the balancing device 54 is disposed in a recess 54 a of the coupling housing 12 above the position that the ball head 16 in the coupling position of the coupling unit 14 occupies.
  • the extension of the axis of the compensating device 54 extends through the center of the ball head 16.
  • the recess 54a is formed slotted and are two clamping screws 54b provided for narrowing the slot.
  • the jaw 36 is pivotally mounted on the housing body 12 about an axis extending in the height direction H axis.
  • This axis advantageously passes through the center of the ball head 16 when clutch unit 14 is in the coupling position. Therefore, the invention provides that the recess 54a of the compensating device 54 forming receptacle 54c of the housing body 12 simultaneously forms the upper pivot bearing for the jaw 36.
  • the return spring 56 which tries to keep the jaw 36 in its central, directed counter to the direction of travel F position.
  • FIG. 1 also shown the lower pivot bearing 58 of the jaw 36.
  • the jaw 36 includes an upper portion 36a pivotally supported on said receptacle 54c and a lower portion 36b pivotally supported by the lower pivot bearing 58.
  • the two sections 36a and 36b are fastened to each other by means of two screw connections 36c.
  • the trailer coupling 10 also comprises two latching levers 60 which engage the catching mouth 36 from behind and form fixing elements for the catching mouth 36.
  • the two locking levers 60 are also pivotally mounted on the axis A, wherein they are rotatably connected via positive locking means 60a with the coupling unit 14 (see also FIG. 7 ).
  • These positive locking means 60a are formed as projections on sleeves 60b which project laterally from the locking levers 60, pass through the side parts 28b of the driver element 28 and engage in associated recesses 14g of the coupling unit 14.
  • the torsion spring 32 Due to the rotationally fixed connection of the locking lever 60 with the coupling unit 14, the torsion spring 32 also biases the locking lever 60, in the representation of FIG. 1 counterclockwise, ie to the jaw 36 too. Thus, supporting the engagement of one of the detent levers 60 on the capture mouth 36, the torsion spring 32 assists the return spring 56 in its effort to transfer the capture mouth 36 to its centered position. If the jaw 36 has reached this centered position, then both detent levers 60 rest on the catching jaw 36 under the bias of the torsion spring 32 and hold it in the centered position.
  • the housing body 12 of the trailer coupling 10 does not need to be a forged part, but can be composed of a plurality of housing plates.
  • the housing body 12 comprises two lateral housing plates 70 and 72, on which the fastening bolts 24 are arranged for attachment of the trailer coupling 10 to the towing vehicle 26 (see also FIG. 6 ) and on which the ramp 34 is attached via two fastening bolts 34c.
  • the housing body comprises an upper housing plate 74, in which the recess 52b is formed for the indicator pin 52a of the display device 52 and which has the receptacle for the compensating device 54 to compensate for the vertical coupling clearance, which also serves as the upper pivot bearing for the jaw 36.
